I manage a telemetry system that uses 4 frequencies to poll various remote sites. On one of our frequencies communications are fine except every hour or so all sites have communications failure through one polling cycle. Using our HMI software I started a text file to show communications coming through the serial port at the time of the communication failure and on every site the modbus query looked fine but the modbus response displayed, in hex, '[15]'.
I looked in some modbus manuals but could not find out what this value signifies.
If anyone can tell me what this means, I would really appreciate it.
Thanks!
